Which of the following actions helps establish a secure environment for mixing/loading chemicals?

Implementing a visitors' log is crucial in establishing a secure environment for mixing and loading chemicals because it enhances accountability and security. By tracking who enters and exits the area, operators can monitor access to sensitive locations where chemicals are handled. This practice helps ensure that only authorized personnel are present, thus reducing the risk of accidental exposure, theft, or unauthorized use of the chemicals. It also facilitates communication and coordination among team members and can quickly identify potential safety breaches or incidents. By maintaining a comprehensive record of visitors, operators are better equipped to enforce safety protocols and respond to emergencies effectively.
